The architecture office Lechner & Lechner was opened by Christine & Horst Lechner in 1987 and re-founded in 2015 as lechner-lechner-lechner ZT gmbh. In the course of the collaboration with the Chair of Urban Development at the ETH Zurich at the end of the 1990s, we met the architect Johannes Schallhammer. Since 2000 we have been working together in an office community at our common location in Salzburg's Priesterhausgasse.
